It means that the mineral is 7.0 times more dense than water at 4^@C.

Explanation:

The specific gravity (also called relative density) of a material is a ratio of the density of that material to the density of water at 4^@C, which is the temperature at which water has its maximum density.
Density itself is defined as mass per unit volume : rho=m/V.

thereforeSG=rho_(rel)=(rho_s)/(rho_(water at 4^@C).
